CNC engraving cutter for wood and plastics

This carbide end mill has two straight flutes and a tungsten steel body. It is supplied as a single piece for CNC routers that need precise engraving and cutting. The tool works on acrylic, PVC, nylon, resin, wood and plywood. It is intended for industrial cutting only and not for anyone under 18 years.

Upgrade from worn single-flute

A fresh two-flute carbide cutter removes material faster and leaves a cleaner edge than a dull or softer bit. The jump is worth it when finish quality drops or feed rates must be reduced to avoid tear-out on fine detail work.

Fits standard ER collets and CNC spindles

The shank dimensions match common collet sizes so no adapter is required. The straight-flute geometry clears chips upward, reducing recutting in shallow pockets. The cutter frees up spindle time by allowing higher feed rates on the listed materials.

Questions about this item

What shank diameter does the 4X4X12X45 end mill require in the collet?

The cutter has a 4 mm shank, so it fits a 4 mm ER collet or shrink-fit holder without adapters.

How deep should the flute length be set in the tool holder for the 12 mm cutting length?

Clamp the shank so the full 12 mm flute length clears the holder face; leaving flute inside the collet causes vibration and breakage.

When should the tungsten steel cutter be replaced during wood and acrylic CNC work?

Replace it when edges show chipping, surface finish degrades, or cutting forces rise sharply — typically after extended use in abrasive materials.
